Solve x(x-5)=0; the roots are 0 and 5.

Draw a number line.  Plot 0 and 5 on this line.  
Set up 3 intervals, as follows:  (-infinity, 0), (0, 5), and (5, infinity).

Now choose a test number from within each interval (e. g., -2, 3, 10).

Subst. each into the inequality x(x-5)\geq 0.  In each case, determine whether the inequality is true or false.  

Based upon your results here, you should be able to determine on which interval or intervals the inequality is true.  Those interval(s) is/are your solution set.

Write an equation in slope-intercept form that passes through (2, -3) and slope of -5.
Ksivusya [100]

Step-by-step explanation:

Hey there!

The given slope is "-5" and it passes through point (2,-3).

<u>Use</u><u> </u><u>one</u><u>-point</u><u> formula</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>out</u><u> the</u><u> equation</u><u>.</u>

<u>(y - y1) = m(x - x1)</u>

<u>Pu</u><u>t</u><u> all</u><u> values</u><u>.</u>

<u>(y  + 3) =  - 5(x - 2)</u>

<u>Simpl</u><u>ify</u><u> it</u><u>.</u>

<u>(y + 3) =   - 5x + 10</u>

<u>y  =  - 5x + 10 - 3</u>

<u>y =  - 5x + 7</u>

The number of bocks has 9 in the ones place. The number in the hundreds place is one more then the tens place. Those two numbers
ella [17]

There are 659 blocks

<em><u>Solution:</u></em>

The number in ones place is 9

Let's denote number in the tens place with x

The number in the hundreds place is one more then the tens place

Therefore,

The number in hundreds place is 1 + x

Those two numbers equal 11

Which means tens place number and hundreds place number sums up to 11

tens place + hundreds place = 11

x + 1 + x = 11

2x = 11 - 1

2x = 10

x = 5

Thus number in tens place = x = 5

Number in hundreds place = 1 + x = 1 + 5 = 6

The number is represented as:

Number = (Number in hundreds place)(number in tens place)(number in ones place)

Number = 659

Thus 659 blocks are there

Rearrange the equation so x is the independent variable.<br>6x+y=4x+11y<br>y=______
Elan Coil [88]

Answer: y = 0.2 x

Step-by-step explanation:

Since, a variable whose variation does not depend on that of another is called independent variable.

Here, given expression is,

6 x +y = 4 x +11 y

⇒ 6 x - 4 x + y = 11 y

⇒ 2 x = 11 y -y

⇒ 2 x = 10 y

⇒ 0.2 x = y

Thus, the value of x does not dependent on the value of y.

Therefore, x is independent variable.

Thus, required answer is y = 0.2 x.
